MACHINE FOR MAKING SIDE-BAR SPRINGS.

SPECIFICATION formingpart of Letters Patent No. 407,913, dated July 30, 1889.

Application filed April 24:, 1889. Serial 1%.308A9Z. (No 11104191.)

To all whom it may concern.-

Be it known that I, MARQUIS D. L. l/VIL- LIAus, a citizen of the United States, residing at Poughkeepsie, in the county of Dutchess and State of New York, have invented certain new and useful Improvements in Machinery for the Manufacture of the Storm, J r., Spring for Side-Bar Wagons, called a Spring-Former; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters or figures of reference marked thereon,which form a part of this specification.

My invention relates to machinery for the manufacture of the Storm, J r., spring for side-barwagons, and is called a springforiner.

The drawings accompanying this specification and in their various diagrams show the machine complete.

The figures and letters on the drawings are explained as follows:

Similar letters refer to similar parts throughout the several views.

Figure 1 is a top view of the spring-former, with a spring already formed in the machine, a being the former proper, which is fastened to a solid post or bed and bolted down by bolts 1) b b. O is a hand-wheel and clamp for holding the hot steel in' position while being formed. (Z is a lever attached to the former by a pivot and pivotal hinge e, the object of the pivotal hinge being to give the lever d either a horizontal or vertical motion without detaching the same from the former, both of which motions are required in-the forming of the spring, and to assist the operator in placing the hot steel beneath the clamp C, and also in removing the spring from the former after being formed, when it is thrown into oil and tempered, being completed with the one heat. f and ff are loose rollers attached by bolts to the braces g g, which are in turn attached to the lever d, the rollers being pressed horizontally against the hot steel, forcing the steel around the former, the roller ff at the end of the braces g g carrying the steelup and over the riser h, when the roller f crowds the hot steel to the former, and the shoe i, which is attached to and under the lever d, presses the hot spring after being formed to the track of the former Z, and by a downward pressure by the operator on thelever (Z'gives the spring after being formed its proper shape and set, as shown more clearly in Fig. 3. I

Fig. 2 is an end vertical view of the springformer. Fig. 3 is a side vertical view of the spring-former. Fig/l is the lever d and the rollers f and f f and the pivot and pivotal hinge e detached from the former. .Fig. 5 is a spring before and after being formed by the spring-former, a being the spring formed complete.

These springs are placed on a wagon in a right and left handed manner; hence it is necessary to make two spring-formers right and left handed, and the two spring-formers are identical and are used for exactly the same purpose, and the description of oneis identical with the other in every detail, except that they are right and left handed, so that this specification is made to cover both a right and left handed spring-former forthe manufacture of the Storm, J r., spring for side-bar wagons.

I do not claim the spring as an article, for that is not my invention; but

WVhat I doclaim, and desire to secure by Letters Patent, isv The machine herein described and represented for forming said springs.

In testimony whereof I hereto affix my signature in presence of two witnesses.

MARQUIS D. L. \VILLIAMS.
